This was a well scoped game, with a solid use of community assets. Loved how you worked in Nowis' stuff again, as well as the whole MZ and MV crew. Story was decent enough, with some enjoyable writing and little moments that hinted at the history the crew had together, like Lucius killing demon lords with light attacks all the time (thanks for making Lucius strong haha!)
I thought the fights were a bit trying on my patience. Waiting for 12 characters to all do their moves made me zone out a bit. There wasn't very good skill balance either. Against a big group of 8, there was pretty much no match for AoE attacks (I think) and all the single target attacks seemed underpowered. Buffs didn't feel worth it, and TP attacks were weaker than their MP counterparts.
If combat were tightened up, sped up, and balanced a bit, that would have made a big impact on gameplay score for sure.
Lastly, can't help but drop some gamejam tips, which you may have already absorbed! Uploading early is super important, as is testing your deployment. It's always sad to see an entry not quite make it, but it happens every year! Still, hope you got some good feedback and that the jam has been valuable to you.
